Are you using ChatGPT or Google Gemini?
If yes, then you are already an expert in the power of LLMs.
Large Language Models (LLMs) are one of the most famous tools in Artificial Intelligence today. They can read, understand, and create text just like humans. From writing content to answering questions, LLMs are changing the way we work, learn and think.
What Are LLMs in AI?
An LLM (Large Language Model) works like AI that understands and creates text just like a human.
It is trained on a large amount of text data, websites, books, blogs, and many more.
Considered this a super and expert tool which can:
- Answer questions.
- Write blogs or emails.
- Translate languages.
- Help with coding.
If I say in my final words, LLMs are a search engine behind modern AI chatbots.
How Do LLMs Work?
The work of LLMs can be explained in three simple steps:
Read a lot of text: The system is trained on billions of words.
Learn patterns: It studies how words perfectly go together.
- Guess the next word: It can suggest the next word you need to write, just like your mobile phone keypad, but AI can do it on a broader level.
Just see LLMs as advanced autocomplete models, although instead of completing one word, they can write complete blogs, stories and even code.
Examples of LLMs
Here are some common examples of LLMs that people use daily.
- ChatGPT (OpenAI): The most usable AI model we are using for FAQs and writing content.
- Google Gemini: A Perfect assistant with text and image understanding. But these days, Gemini is too busy making magical photos. Personally, I’m using Gemini to create thumbnails and also graphics work for my blogs.
- Microsoft Copilot: This tool from Microsoft can help in Word, Excel, and other applications.
- Claude: Known for safer and longer conversations.
- Meta LLaMA: Popular open source model for people who are doing research and for developers.
Top and Most Popular LLMs in 2025
LLMs are upgrading fast, and a number of companies have released powerful versions. Here are some of the top LLMs these days:
- GPT-4o / GPT-5 (OpenAI): Advanced reasoning and a lot of features.
- Gemini (Google DeepMind): Works with text, images. Google is also upgrading to work with videos soon.
- Claude 3 (Anthropic): Focus on ethical AI and long memory.
- LLaMA 3 (Meta): Open source, mostly used for research.
- Mistral AI: A lightweight and fast system for businesses.
- Cohere Command R+: Famous for retrieval augmented generation (RAG).
Some models are closed source, like GPT-4 and Gemini, but others are open source, like LLaMA and Mistral. Businesses mostly choose based on cost, control, and use case.
Generative AI and LLMs for Dummies
Generative AI means AI that creates new things, text, images, music, or video.
- LLMs are a type of Generative AI that emphasise only text.
- Example: ChatGPT writing an essay is a Generative AI powered by an LLM.
So, we can say that all LLMs are part of Generative AI, but not all Generative AI is an LLM.
